BICYCLE.

SPECIFICATION forming part of Letters Patent NO. 588,274, dated August17, 1897.

Application filed January, 16, 1897. Serial No. 619,450. (No model.)

To all whom it may concern:

Be itknown that 1, CHARLES R. HARRIS, a resident of \Villiamsport, inthe county of Lycoming and State of Pennsylvania, have invented certainnew and useful Improvements in Bicycles; and I do hereby declare thefollowing to be a full, clear, and exact description of theinvention,such as willenable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improvement in bicycles, the object being toprovide a vertically-resilient and laterally-braced bicycleframe forgentlemen riders; and it consists in certain novel features ofconstruction and combinations of parts, which will be hereinafterdescribed,and pointed out in the claims.

In the accompanying drawings, Figure 1 is a viewin side elevation of'myimproved machine. Fig. 2 is a plan view, and Fig. 3 is a transversesectional view.

A represents the steering-head of a bicycle, B the front and G the rearwheels, and D is the frame. This frame is composed of tubular metalapproximately semicircular or D- shaped in cross-section. Two of thesetubes are used, and they are so placed or disposed that their fiat facesare turned toward each other. The tubes constituting the frame startfrom the steering-headat l with their fiat faces brazed or otherwisesecured together; From this point the frame first curves graduallydownward and rearward to a point 2, where the two tubes composing itspread apart laterally. extends in a general horizontal and rearwarddirection on each side of the rear wheel,thence upward and again forwardas faras the point 3, where the seat is located. At this point 3 the twotubes join each other again and-extend downward as a single tube to apoint 4, where they spread apart again. From this I point at the ends ofthe tube extend together From this point the frame wheel is housed andthe tubes of the frame form a guard which keeps the riders trousers fromcatching in the sprocket-Wheel, the frame itself projecting farenoughlaterally to insure it.

neat-appearing frame is formed having great vertical resiliency and withrigid lateral bracing.

It is evident that slight changes might be made in the form andarrangement of the several parts described without departing from thespirit and scope of my invention, and hence I do not wish to .limitmyself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a bicycle, a frame composed of two semicylindrical tubes havingtheir fiat faces secured together atone end and spread apart laterallyat other points, these tubes bent around in a continuous curve or sweepand finally down again where they terminate and are joined together ator near the point where the tubes first spread laterally.

2. In a bicycle, aframe composed of two semicylindrical tubes havingtheir fiat faces secured together at one end and from this point spreadapart laterally, these. tubes bent around in a continuous curve or sweepand finally down again where they terminate by merging into the tubes ator near the pointwhere the tubes first spread apart, a bar ex tendingforward from the upper portion of minating in an up\\'ardly-bent endwhich is hollow and forms a socket for a seat-post.

L. The combination with a frame bent in a gradual and continuous curveand one end joined to the frame some distance rearward from the otherend, of a bracket secured in the space formed between and immediatelyrearward of these joined portions, a crankshaft revoiubl y supported inthis bracket, and

a mud-guard secured in the frame above this 10 crank-shaft.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

CHARLES R. HARRIS.
